Abstract: A conference on construction industry productivity at Lincolnshire, Ill., in August 1976 is reported. Improving productivity in designing, constructing, and operating facilities is central to the health of the construction industry. Suggestions are made for improvements in these areas. Top management support for the philosophy and the requirements of the control system, along with timely data collection and analysis produce tangible results. The main responsibility in design and construction rests with management, and management should take fresh approaches to solving productivity problems. The ASCE Committee on Engineering Management should work in this area and seek generalized and specialized definitions and methods of measuring productivity. It should collect, analyze, and disseminate productivity data in design and construction, and foster development of positive productivity improvement approaches.
